Recent Findings from University of Basque Country Provides New Insights into Nanoparticles (Polymer/silica nanohybrids by means of tetraethoxysilane sol-gel condensation onto waterborne polyurethane particles)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nanoparticles have been published. According to news reporting originating in Donostia San Sebastian, Spain, by NewsRx journalists, research stated, "Stable waterborne polyurethane/silica hybrid dispersions were obtained by sol-gel reaction of tetraethoxysilane added to previously synthesized waterborne polyurethane nanodispersions. Two series of polyurethane/silica nanostructures with different silica contents were synthesized using pure polyurethane particles and polyurethane particles previously functionalized with (3-aminopropyl)triethoxysilane (APTES) as colloidal templates."

The news reporters obtained a quote from the research from the University of Basque Country, "The optimum experimental conditions for tetraethoxysilane sol-gel reaction (T=75 degrees C and semi batch polymerization conditions) leading to the formation of silica/polyurethane aqueous nanodispersions were established. The presence of silica was confirmed using TGA, FTIR, Si-29 NMR and TEM."

According to the news reporters, the research concluded: "TEM images showed an excellent final dispersion of the silica nanoparticles in the polymer matrix when silane functionalized polyurethane nanoparticles were used."
